Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, operation is light, cost of production is low door and window transmission handle.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of door and window handle, comprise main body, and described main body is provided with cavity, and described main body is provided with cover plate.
Described main body is provided with at least one connecting hole, and described cover plate is provided with at least one joint pin, and described joint pin and described connecting hole cooperatively interact.
Described cover plate can be wooden cover plate, plastic cover plate after the surfacing and metal cover board.
Described joint pin is three, and described connecting hole is three.
Described joint pin is provided with groove.
Described door and window handle comprises main body, and described main body is provided with cavity, and described main body is provided with cover plate, and described door and window Handle axis is connected on the described axle bed, and described axle bed is provided with transmission mechanism.
Described transmission mechanism comprises travelling gear and the tooth bar that cooperatively interacts with described travelling gear, be wholely set central axis on the described travelling gear, described spigot shaft coaxle passes described axle bed and is connected with described handle, the coaxial axle sleeve that is arranged with between described central axis and the described axle bed is provided with the elastic positioning machine structure between described axle bed and the described central axis.
Described elastic positioning machine structure comprises the coaxial spacer that is fixed on the described central axis, the edge of described spacer is provided with four equally distributed grooves, the edge of described axle bed is provided with four equally distributed spring bases, be respectively arranged with spring on the described spring base, described spring is provided with steel ball.
Be wholely set lock point dop on the described tooth bar.
Compared with prior art, the invention has the advantages that the main body of handle is provided with cavity, main body is provided with cover plate, makes the handle quality lighter, and material is more economized, and cost of production is lower.
Joint pin is provided with groove, can make cooperate between cover plate and the main body more firm.
And be provided with the elastic positioning machine structure in the transmission mechanism, the handle revolution just can be located for moving 90 °.
